This error was detected while a MEX-file was running. If the MEX-file
is not an official MathWorks function, please examine its source code
for errors. Please consult the External Interfaces Guide for information
on debugging MEX-files.

So, I use the following command to run MATLAB

/fullpath of MATLAB/matlab -softwareopengl

Then, when I try to open a simulink model, MATLAB crashes.

Anyone has ideas? I have attached the error below.

Thanks.

This error was detected while a MEX-file was running. If the MEX-file
is not an official MathWorks function, please examine its source code
for errors. Please consult the External Interfaces Guide for information
on debugging MEX-files.

Answer 1

[Yunsik Jung]

[Xingwang Yong]
